The title compound, [Tc(CO)(6)]ClO(4), was synthesized by the reaction of [TcCl(CO)(5)] with AgClO(4), followed by acidification with HClO(4) under a CO atmosphere. The Tc(CO)(6) cation has close to idealized octa-hedral geometry, with the bond angles between cis-CO groups close to 90° and the Tc-C bond lengths in the range 2.025 (3)-2.029 (3)Å. The perchlorate anion is disordered over two crystallographically equivalent half-occupied positions. The Tc atom in the Tc(CO)(6) cation is located on an inversion centre.

标题化合物[Tc(CO)₆]ClO₄是通过[TcCl(CO)₅]与AgClO₄反应，然后在CO气氛下用HClO₄酸化合成的。[Tc(CO)₆]⁺阳离子具有接近理想的八面体几何构型，顺式CO基团之间的键角接近90°，Tc-C键长在2.025 (3)-2.029 (3)Å范围内。高氯酸根阴离子在两个晶体学上等效的半占据位置上无序分布。[Tc(CO)₆]⁺阳离子中的Tc原子位于一个对称中心上。
